An Alto Shaam SN-34690 Flame Sensor detects burner flame presence to maintain safe, reliable heating in the system.
The flame sensor detects burner flame presence and communicates that status to the control system so fuel delivery and ignition sequencing stay properly regulated during operation. Its design matters because accurate flame sensing supports safe burner control, reduces nuisance shutdowns and maintains dependable heating performance under normal operating conditions.
The flame sensor may be failing if the equipment shows ignition problems, intermittent burner shutdowns, error conditions or inconsistent heating during use. Common indicators include corrosion, carbon buildup, discoloration, loose connections or exposure to heat and moisture that can interfere with accurate flame detection.
